Dehler
Advanced engineering for high-performance circuit isolation and protection.
The global demand for high-reliability isolating switches is surging, driven by the shift toward Smart Grids and Renewable Energy. Modern procurement officers now prioritize manufacturers who offer digital twin compatibility, high short-circuit withstand capabilities, and SF6-free environmentally friendly insulation.
Adhering to IEC 62271-102 and IEEE C37.30.1 standards is no longer optional. Our disconnectors undergo rigorous Type Testing to ensure performance under extreme temperatures and seismic conditions, providing a 30-year operational life with minimal maintenance.
We are transitioning from traditional mechanical disconnectors to Intelligent Isolating Switches integrated with IoT sensors. These devices provide real-time thermal monitoring and mechanical wear prediction, drastically reducing downtime in critical infrastructure.
An Isolating Switch (or Disconnector) is a critical safety component that ensures a circuit is completely de-energized for maintenance or repair. Unlike circuit breakers, which are designed to interrupt load and fault currents, the isolating switch provides a visible physical break in the circuit, ensuring the safety of personnel. At Dehler Technology, we understand that in a high-voltage environment, "visible safety" is the ultimate requirement.
Established in 2016 and located in the Yanpan Economic Development Zone, Yueqing City, Dehler Technology Co., Ltd. has grown into a powerhouse of R&D and manufacturing. We operate two specialized divisions: our main headquarters for high/low voltage switchgear and a dedicated Transformer Division at No. 178 Jingba Road.
Our philosophy is simple: "Survival through quality, development through technology." This core belief drives our production of high-performance indoor and outdoor vacuum circuit breakers, disconnectors, and earthing switches that meet the diverse needs of modern power grids.
